Ive got some TR6's that saw about two bottles sprayed through them about 20k miles ago when i first swapped them. I havent sprayed since, will i need to swap them out before i spray a 100 again?

Whats the usual mileage interval on plugs that see n20? Thanks!

If you are not fine tuning your combination, there is no real time frame.
What I do is check for sharpness in the edges.
If you are pitting the piston, or fouling the plugs, obviously you want them out of there.
A good running combination should keep the plugs clean, and operating properly until you round over the edges.

Just letting you know that a TR6 is a projected tip plug but you are on a small shot. You might want to change out to a br6ef which is non projected just as a little insurance policy.

I have a set of br7efs that I haven't installed cuz I heard of people with daily driver issues with them. Maybe the br6ef would be a Good compromise

I would never use a projected tip, but I know guys that do all the time with those tiny kits.
I would not worry, but next time you might think about getting fresh plugs without the projected tip.

Good luck.
